SPINNING-SPINDLE Specification of Letters Patent.

Patented July 23, 1907 Original application iled December 22,1904,Serial No. 237,876. Divided and this application filed November 6,1906.

Serial No. 342.304.

To all whom it may concern:

Be it known that I, DAVID LEMOINE, a citizen of the United States,residing at Fisherville, in the county of vWorcester and State ofMassachusetts, have invented a new and useful Spinning-Spindle, of whichthe following is a specification.

This application for patent is a division of my prior application filedDecember 22, 1904, Serial No. 237,876.

The object of this invention is to improve the ordinary spinningspindle, particularly with respect to the way in which the bobbin isheld thereon and also with respect to the bearings and the balancing ofthe spindle.

A spinning spindle made according to my invention is shown in theaccompanying sheet of drawings forniing a part of this specication.

In the drawing, Figure 1 is a sectional elevation of a spinning spindle'embodying my improvements, and Fig. 2 is a plan view partly in sectionof the bobbin gripping cup.

Referring to the drawings and in detail, 18 designates the blade. Thisis Inade out of steel and hardened and ground, and the upper taperedpart of the saine is made slightly smaller than usual. Then fitted onthe same is a whirl 19 which has an extending jacket or thin sleeve 20which is bored out so that the upper tapered portion of the blade can beforced into the same, This jacket or sleeve 20 extends to the tip of theblade and forms the bobbin engaging or supporting surface. The whirl andjacket are preferably made in one piece and are roughly finished beforethe blade is forced into the same. The jacket or sleeve 20 is thenaccurately finished off. This will make a balanced and true spindle.This has been claimed in my above mentioned application.

2l designates a bobbin clamping cup which is forced onto the combinedjacket and whirl. This cup has four holes drilled at right angles toeach other, the

inside ends of the holes being smaller than the main portions thereof.Fitting in these holes are plungers 22 which have projecting endsextending through the reduced portions of the holes. Springs 23 arearranged to bear o n the plungers, and the outside of the ends of theholes are closed by plugs 24 which are forced into the holes. i

By this construction when a bobbin is placed upon the spindle the lowerend thereof can be forced down into the bottom clamping cup so that theplungers thereof will tightly grip and hold the same. It will be seenthat the plungers are arranged to act inwardly and independently of eachother, whereby the bobbin will be tightly and accuratelyheld even ifirregular in shape.

By the arrangements before described a balanced spindle is providedwhich can be run at high speed, and in which the bobbin will be clampedand held tightly as the yarn is wound thereon.

The details and arrangements herein described may be varied by a skilledmechanic without departing from the scope of my invention as expressedin the claims.

Having thus fully described my invention, what I claim and desire tosecure by Letters-Patent is l. A spinning spindle comprising a blade, acombined Whirl and jacket secured thereto, a bobbin clamping' cupsecured to the jacket, and having inwardly acting bobbinclampingplungers.

2. A spinning spindle comprising a combined whirl and jacket, the jacketboing adapted to support the bobbin in contact with its outer surface,and inwardly extending spring-pressed plungers mounted above andsupported by the whirl for clamping the bobbin against the jacket.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.

DAVID LEMOINE.
